Static Ram component address bus width limited to 18 bits

In the current implementation of the static ram component, the address bus width is limited to 18 bits.
Could it be possible to extend it to 20 bits ?
This way it could be used to simulate components like a AS6C4008-55PCN

You can make a scheme from 2 or 4 RAM/ROM components available in the program. It will be faster than waiting for the program to be finalized.

I don't remember the reason to limit the address size to 18...

New limit to 24 bits at Rev 1080.
